Description

Technical Field

[0001] The utility model relates to the technical field of pipeline pressure measurement, in particular to a pipeline pressure measuring instrument. Background Art

[0002] After the fire protection, water supply, PPR / PERT / PE / PB and other pipelines are installed and connected, the pipeline needs to be tested for internal pressure before the next step, so as to timely find leaks or seepage in the pipeline. If leaks or seepage are found, it is convenient to make timely rectification to avoid leaks or seepage in the pipeline during operation. When testing the sealing of the pipeline, a pressure device is needed to inject water of a certain pressure into the pipeline for pressure maintenance testing. The change of water pressure in the pipeline can be used to judge whether there is any leak or seepage in the pipeline. If the water pressure in the pipeline remains unchanged, it means that the pipeline is sealed and there is no leak or seepage. If the water pressure in the pipeline continues to decrease, it means that there is a leak or seepage in the pipeline.

[0003] In the prior art, a manually operated pressure measuring device is generally used to inject pressurized water into a pipeline. The manual pressure measuring device has low efficiency and is laborious to operate. In addition, the water pressure is difficult to control during manual pressure measuring, and the pressure detection is not accurate enough, which affects the evaluation of the pipeline quality. Therefore, the utility model proposes a pipeline pressure measuring instrument to solve the problems existing in the prior art. Utility Model Content
